Python淘宝或京东等秒杀抢购脚本实现(秒杀脚本)

Python淘宝或京东等秒杀抢购脚本实现，通常需要模拟用户在网站上手动选购商品，提交订单等操作。一般而言，实现秒杀脚本的流程可以分为以下几个步骤：

步骤一：分析目标网站

首先需要了解目标网站的网络通信协议，以及目标页面的HTML结构、JS代码等。通常可以使用浏览器的开发者工具查看页面元素、请求信息、响应数据等，并使用Python的requests、Beautiful Soup、Selenium等第三方库获取和解析页面数据。

步骤二：模拟用户登录

在淘宝或京东等网站进行秒杀抢购需要先完成用户登录。可以通过分析登录请求数据的方式实现模拟自动登录。通常可以使用Python的requests库或Selenium库来模拟POST登录请求。此外，为了避免登录过程中验证码的干扰，可以将其自动识别并填写。

步骤三：请求商品页面

登录后，需要模拟浏览器或其他客户端请求目标商品页面。通常可以使用Python的requests库或Selenium库访问目标商品页面，因为这些库支持Cookies等信息的维护。通过页面元素分析，获取到商品的URL，然后发起请求获取目标页面数据。

步骤四：解析页面数据

解析商品页面，找到需要提交的商品相关参数：包括商品名称、ID、库存数量、价格等信息，以及提交订单时需要的csrf_token等参数。

步骤五：提交订单请求

收集完商品信息和订单参数后，需要使用Python的requests库或Selenium库提交订单请求。在提交订单时需要注意请求的Headers、Cookies等信息是否与浏览器或其他客户端一致，否则可能会被服务器识别为非法请求。同时注意不要在短时间内重复提交订单请求，避免触发服务器的防刷限制。

下面是两个关于Python实现京东秒杀脚本的示例说明：

示例一：使用requests库进行京东秒杀

import requests
import time

# 填写京东登录信息
username = ""
password = ""

# 添加商品到购物车的请求信息
add_cart_url = "https://cart.jd.com/gate.action?pid=商品ID&pcount=1&ptype=1"

# 提交订单的请求信息
order_url = "https://trade.jd.com/shopping/order/submitOrder.action"

# 添加购物车请求的headers
headers = {
    "Referer": "https://item.jd.com/商品ID.html",
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.150 Safari/537.36"
}

# 登录京东
s = requests.Session()
login_url = "https://passport.jd.com/new/login.aspx"
headers['Referer'] = login_url
response = s.get(login_url, headers=headers)
# 通过解析响应HTML，获取登录所需的参数信息
# ...

# 构造登录请求，提交登录信息
login_data = {
    # ...
}
login_url = "https://passport.jd.com/uc/loginService"
headers['Referer'] = "https://passport.jd.com/new/login.aspx"
r = s.post(login_url, data=login_data, headers=headers)
# 若登录成功，则可以添加商品到购物车或者提交订单
data = {
    "overseaPurchaseCookies": "",
    "vendorRemarks": "[]",
    "invoiceEasyInfo": "{'type':4,'invoiceTitleId':'7','invoiceContentId':'1','personalInvoiceTaxpayer':'','enterpriseInvoiceTaxpayer':'','invoicePhone':'','invoicePhoneValidate':0,'invoiceEmail':'','invoiceAreaProvinceId':2,'invoiceAreaCityId':0,'invoiceAreaCountyId':0,'invoiceStreetAddress':'','invoiceAddressId':0}",
    "submitOrderParam.sopNotPutInvoice": "false",
    "submitOrderParam.trackID": "TestTrackId",
    "submitOrderParam.ignorePriceChange": "0",
    "submitOrderParam.btSupport": "",
    "submitOrderParam.eid": "",
    "submitOrderParam.fp": "",
    "submitOrderParam.savePayShipTime": "",
    "submitOrderParam.jxj": "1",
    "submitOrderParam.yuyue": "",
    "submitOrderParam.jdGroup": "8",
    "submitOrderParam.presaleStockSign": "",
    "submitOrderParam.isBestCoupon": "",
    "presaleEndTime": "",
    "presaleStartTime": "",
    "overSeas": "",
    "vendorRemarks": "[]",
    "submitOrderParam.giftCardBalance": "",
    "submitOrderParam.giftCardDiscount": "",
    "submitOrderParam.useUuid": "",
    "submitOrderParam.cardUuid": "",
    "submitOrderParam.isCodPay": "false",
    "submitOrderParam.presalePayTime": "",
    "submitOrderParam.continueFlag": "",
    "submitOrderParam.europe": "",
    "submitOrderParam.sopNotPutInvoice": "false",
    "submitOrderParam.jdPrice": "",
    "submitOrderParam.jdBean": "",
    "submitOrderParam.contentInfo": "{}",
    "submitOrderParam.balancePay": "0",
    "submitOrderParam.useBalance": "false",
    "submitOrderParam.isGlobalMarket": "1",
    "submitOrderParam.cartUuids": "",
    "submitOrderParam.isModifyAddress": "false",
    "submitOrderParam.payPassword": "",
    # fill in other parameters
}

# 添加到购物车
response = s.get(add_cart_url, headers=headers)
if response.status_code == 200:
    # 提交订单
    response = s.post(order_url, data=data, headers=headers)
    if response.status_code == 200:
        pass # 提交成功
    else:
        pass # 提交失败
else:
    pass # 添加购物车失败

示例二：使用Selenium库进行京东秒杀

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as ec
import time

# 填写京东登录信息
username = ""
password = ""

# 初始化浏览器
options = webdriver.ChromeOptions()
options.add_argument("--start-maximized")
driver = webdriver.Chrome(options=options)
driver.implicitly_wait(10)

# 登录京东
login_url = "https://passport.jd.com/new/login.aspx"
driver.get(login_url)
driver.find_element(By.ID, "loginname").send_keys(username)
driver.find_element(By.ID, "nloginpwd").send_keys(password)
driver.find_element(By.ID, "loginsubmit").click()

# 添加商品到购物车
item_url = "https://item.jd.com/商品ID.html"
driver.get(item_url)
try:
    cart = WebDriverWait(driver, 10).until(ec.element_to_be_clickable((By.ID, "InitCartUrl")))
    cart.click()
except Exception as e:
    print(e)

# 提交订单
try:
    order_submit = WebDriverWait(driver, 10).until(ec.element_to_be_clickable((By.ID, "order-submit")))
    order_submit.click()
    time.sleep(0.5)
    confirm_order = WebDriverWait(driver, 10).until(ec.element_to_be_clickable((By.ID, "order-submit")))
    confirm_order.click()
    print("订单提交成功")
except Exception as e:
    print(e)

# 关闭浏览器
driver.quit()

注意事项：

以上代码仅作示例演示，实际使用时需要根据所购商品的实际HTML结构及页面操作进行相应的调整；
开发过程中需要遵守网络安全法及相关法律法规，不要使用脚本对目标网站进行恶意攻击或非法操作。
